QT532G-25.000MAHE-T

Overview

The QT532G-25.000MAHE-T is a surface-mount quartz crystal resonator manufactured by QST, operating at a nominal frequency of 25 MHz. It features a load capacitance of 12 pF and an equivalent series resistance of 50 Ohms. The component exhibits a frequency stability and tolerance of ±30 ppm across the operating temperature range of -40°C to +85°C. It utilizes a 2-SMD, no lead package with dimensions of 5.0 mm x 3.2 mm x 1.2 mm.

Feature Summary

• Seam seal construction for environmental protection
• Wide industrial temperature operation capability
• Surface mount design for automated assembly

Applications

• Industrial control systems
• Automotive electronics
• Microcontroller clock sources

Procurement Notes

Verify the manufacturer designation as QST or TXC on official datasheets, as both entities are associated with this part number family. Confirm the specific suffix matches the required frequency and tolerance specifications. Ensure the package dimensions align with the PCB footprint requirements before finalizing procurement orders.

Selection Notes

Select this component when a 25 MHz reference is required for circuits operating in harsh environments. The ±30 ppm stability suits general timing applications where high precision is not critical. Verify that the 12 pF load capacitance matches the oscillator circuit design parameters to ensure accurate frequency generation.

Part Context

This part belongs to the QT532G series of seam seal crystals. The series offers various frequencies within the same 5.0x3.2x1.2 mm form factor. Similar parts include the QT532G-20.000MAHE-T and QT532G-24.000MAHE-T, which share identical physical dimensions and electrical characteristics but differ in nominal frequency.

Replacement Considerations

Direct substitutes within the same series include QT532G-25.000MAHJ-T if different load capacitance is acceptable. Cross-manufacturer replacements require matching the 25 MHz frequency, 12 pF load capacitance, and 50 Ohm ESR specifications.
